Abstract (en)
A water pump assembly (10) for an internal combustion engine including a housing (12,14), as well as first and second rotatable shafts (40,23) supported by the housing. First and second pulleys (48,30) are fixed for rotation with the first and second shafts, respectively. A pumping member (18) is fixed for rotation with the second shaft. A flexible member (50) engages the first and second pulleys and is sized to slip relative to one of the first and second pulleys when in an unloaded state. A control mechanism (70) selectively applies a load to the flexible member to cease the slipping and drivingly interconnect the first and second pulleys to rotate the pumping member.
